The SINGLEstream SS-2206BT-BT-S Link Aggregation Tap is inserted inline and can collect traffic from two network links and allow you to combine traffic into a single output. With 2 monitoring ports, you can have 2 copies of that aggregate data, or keep the full duplex streams seperate, when utilization is high. For additional flexibility, the monitor ports, 5 and 6 can also receive traffic from an external mirror port or another tap. The SS-2206BT-BT-S is popular in primary / secondary connections where a single tool is necessary to capture traffic from either link, no matter which one is up and running.
